Normals are vectors in computer graphics that define the exterior surface of a geometry and the direction the surface is facing. Normals may also be called “Surface Normals”, but usually are referred as “normals”, are used in 3D applications to help render the polygon on the screen by distinguishing the front and back side of each primitive.

SDF used to Deform Geometry

Building upon that collision detection, we can also use the SDF to deform the object upon the collision. Using the SDF value and some math, the grid can be deformed to create footprints stamped on by the Torus.
